Subject: [PATCH] scsi: hpsa: Remove unreachable code
Date:   Mon, 17 Apr 2023 18:07:57 +0300
Message-Id: <20230417150757.62902-1-artem.chernyshev@red-soft.ru>

hpsa_lookup_board_id() can't return negative value, so we can
remove redundant if-statement

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: c8cd71f1f32a ("scsi: hpsa: Remove 'hpsa_allow_any' module option")
